.BOBBIN WAXING MACHINE Filed May 12, 1945 Patented Aug. 17, 1948 DavisMarins'ky and Louis H. Morin, Bronx, N. Y.; Louis -H. Mor'executor ofestate of said DavisY :i: Marinsky, deceased This invention relates tomachines for waxing bobbins and similar strand wound bodies,fparticularly wherein the strands are cross-wound. More particularly, theinvention deals with a machine which is' 's o constructed that fixedstandards in the waxing of bobbins may be maine` tained in all bobbinscfa particular type and kindprocessed in the machine, this result beingaccomplished by maintaining a predetermined temperature in the wax bathby accurately time ing Athe immersion period of the bobbins and alsoinaccurately controlling the time period of spinning for removal 'ordisplacement of excess wax. 1 A 1 The novel features ofthe inventionwill be best understood from the' following description, when takentogether" )with the accompanying drawing, in which certainembodimentswof,the invention are disclosed and,` in which,r th'e separate parts aredesignated by suitable referenceVV characters in each ofthe views and inwhich:

In Fig, 1 of the drawing,j In represents part of a table or 'frame of amachine, upon which is arranged an upstanding support and guide plateII, havingvertically spaced bearings'` vI2 an'dl3 for a reciprocatingrod I4. lThe rod' I4 carries atitsupper end a bracket I5, to oneextension IG ofwhich is secured a high-speed electric motorj f soumis;

motor having means for quickly stopping the rotation thereof. y'I hebracket I5 has another extension terminating in a vertically arrangedvbearing I8, in which is disposed a shaft I9. The upper end of the shaft'I9 carries a V-pulley 20,

around which passes a belt 2I which also passes Varound a pulley 22 onthe shaft of the motor I1. The shaft I9 beneath the bearing I8 has acollar 2 3 against which seats va coil Spring 2L The spring"24 operatesa cup-shaped cap`25 slid-f ably engaging the shaft and adaptedftoengagethe upper end 'of the hub portion 2B 'of 'a basket or carrier A2l.

' The'basket; orcarrierll is shown iridetail'in thereohfin which. thesquare; end 3310i the shaft4 is adapted to..closely tfto key theibasket21;

TheA `spring-pressed collar uponv the shaft I9. 25; serves. to supportthe 'basketin' coupledand keyed; relation with the: shaft I 9,'as isclearly' illustrated in Figs. v1"'and3'ofjthe drawing;l Itwillbeapparent, however, that. by pushing. up-

wardly on the collar 25, the hub 26 may be moved.

upwardly to disengage the headl 33 from the:

socket. 34 permitting detachment ofthe/basket 2.1. lIn assemblingtheribasket, the lsame operation takes place,that is;'the'collar 25"israised v permitting attachment of thebasket'in 'coupling engagement withthe head33.

' The supporting vframe YI I :has at its'upper vendadownwardly-extending hook portion 35i,-be1ow` which and inalinementwith -which is a 'shelfv portion36; `The h ook'and shelf are sospaced as to receivev and A`detahably support a -tank 31 manner clearlyillustrated in Fig. '1,

'Itiwill appear that by-'placing oneupper edge 0f the tank beneath thehook-35withjthe tank-I in a tilted positiomthe tankmay be then movedsito position with' the bottom wall 13a thereof resting upon the shelf36. The ldwer por'tionfof theltank spaced with respect to the shelf hasfa d0wn`wardly directed extension 39,' in whichA is disposed abulb 4 0 ofa temperaturek controlv in-lk strument'. 4 I vwhich instrument is incircuit with eleotrcheating elements 42 in anysuitablefmanl ner'gand, asin, otherfdevice's of this :type and,

kind for controlling the heating elements in maintaining a predeterminedtemperature of the melted wax 43 arranged in the lower portion of thetank 31. The level of the melted wax 43 is maintained in the tank at apoint which will insure complete submersion of the basket 2.1 when movedinto;l itsI lowered position, this level being under the controlV of theoperatorand beingf governed by insertion of additional wax or paraffinin the tank 31.

On the table or frame I l) is arrangeda sllilprtE ing bracket 44 for acam shaft 45 and pivot" 46 for an operating lever 41. The cam shaft isactuated through the medium of a: standard one revolution clutch, notshown, so that in each operation of the machine, theshaft 45 will com.plete one revolution and then come to a stop,

the stopping position being a position whenl a.

roller 48 on the lever 41 is upon the high point of the surface 4B of acam 5I), in which position the basket 21 will be in the raised positionshown in. dotr and dash linesat2y1 in Fig. l ofthe drawing and the lever41 will be in the. raised position indic'atedindot and dash linesv at41.

The'cam SII has. another cam surface 5I operatingiupon theI roller 48'tomaintain the basket 21. in the'sp'inning position. shown in sectionallines in Fig'. '1` of the drawing,.that is to. say, with, the basketdisposed in the top of the tank 3,1 and, above the. melted wax orparaffin therein. At this time, it will be welll to point out that thelever 41" has a forked end 52 engaging e. pin 53 on a flattened portion5 4 of they reciprocatingv rod I4, afslthe roe, I4 moves upwardly' anddownwardly, the basket is carried thereby, as Well as the motor4 I1;

Arranged in the shaft 45 is another cam 55 having Aa raised surface'y 55operatively engaging the` roller 51 of a micro-switch 58 in circuit withthe motor I1 andl a source ofy electric supply through wires 59 and` 6B.

In other words, themicro-switch 58 is actuated to. complete the circuit.to the motor'4 I1 when. the basketI 21i'is in the full 'line positionshown in FlgQl and the motor will continue to operate until the roller.51 dropsfrom the surface. 56, at which time: the motor I1 is.instantaneously stopped and the basket. 2,1 is. then moved into the`raised position, indicated at 21'. the` machine stops facilitating theremoval ofi-the basket with the processed bobbins 29 therein and thevinsertion. of another basket inwhich bobbins to; be:Y processed havebeen placed. Thereupon,

the` machine isagain placed'in: operation by the.

operator and the basket` 21.willv then be moved from the position shownin. '21 to the extreme lowered and submerged position shown at 21"` inEig. 1 of thedrawing, in which position the lever 41 assumes theposition indicated in dot and dash.

lines. at 41". From thesubmerged position, the

basket 21 is then moved intoits raised position.

shown in full lines 1and `the above cycle of operation described is thenrepeated. At the endof;

eachlcycle, the onebasket is-removedandr anew basket substituted.

it. willv be. understood. that the. speed at which` the. shaft 45 is.rotated will in. one respect control.. the processing. of -bobbins orother-.wound strand.

bodies, particularly` when the strand bodies may have, differentcharacteristicsA requiring. longer or shorter. period. of submersionand` spinning or rotation. In some instances, itmay bey necessarytnfincrease` or decrease. the time period of.,sub-.

:nersiomin which event the cam surface 49 would be modified. Onuthe-other' hand, the period of When in this. position spinning or rotationmay be increased or decreased, in which event the cam surface 5I wouldbe modified. In other words, different types of cams would have to beused in the machines. However, in standard products, where many machinesare employed, different machines may have different. characteristics tosuit the differences in the products beingprocessed as and when suchdifferent characteristics prevail. When all products processed in aplant have the same characteristics, then all machines would be operatedon the same basis and under the same controls in order to maintain astandard result the-waxedfbobbins.

By providing the quick detachment of the tank 3.1, this tank may lbequickly removed for cleaning and repair Without disturbing any of theother;` mechanism of the machine.
